It could be that you have a virus and had a bad video card. Are you wounder is it possible for a virus to make your screen go black? the answer is yes it is.
1. I think a Windows have build in APIs function for the monitor blinking thing, I mean when someone changes their screen resolution what happens, it usually blinks right.
2. The virus can be interfering with the video cards Device driver. I really do Not think this is the issue. I think it's a virus plus your video card was going bad.
3. Some Remote access programs have the ability to blank out the end users monitor. So if someone is controlling your computer from some where else, That could be the case.
Whats your opinion?
